OEMM386 is to be configured by adding in CONFIG.SYS file its configuration parameters.
Two configuration modes for OEMM386 are illustrated below.
In CONFIG.SYS insert a string as follows:
DEVICE = drv:\path\OEMM386.SYS NOXRAM
In this case:
64 K is used as extended memory (for OEMM386), the remaining system
memory is expanded memory.
DEVICE = drv:\path\OEMM386.SYS NOXRAM EMS = 0
In this case:
All system memory is extended memory.

Intel no longer supplies 82355 component, therefore 82355SX
component is to be used. Parity is no longer handled with the
introduction of this component.
Component 82355SX can be used on UC093 and 097 from level 03
on, and on UC112 and 113 from original level onwards.
To use the new component, make some trimming and replace a
PAL. See FCO 3877542 R 509.

Can not support PEM device. The new power supply unit PS30/B1
can handle this option.
i860 processor
Customer test diskette does not correctly handle the installation of
this processor.
Possibly new customer test release should handle it.
486 microprocessor
i486 B6 microprocessor is no longer produced. It is replaced by i486
D0 microprocessor that has the same functionalities.
On BA847 motherboard, use of a microprocessor different from
version D0 causes problems on the parallel port that were solved
with level 12.
GO738 (ESC-1)
On hard disk and floppy disk GO738 controller, component 82355
A2 (BMIC) is replaced with component 82355B0 that is functionally
compatible with it. This operation is only to be executed in case of
malfunctioning in field, board level is not changed.

SYSTEM MEMORY MAP
AT standard has a basic memory of 512 KB, expandable up to 640 KB, in which remapping of physical memory areas is not requested.
With a basic memory expansion beyond 640 KB, a logic addressing conflict arises because the
physical memory between 640 KB and 1 MB occupies the logic addressing space reserved for
BIOS ROM addressing. This addressing space between 640 KB and 1 MB is called AT compatibility gap.
In order not to lose this memory space, in these systems a remapping function has been introduced
which makes it possible to have this memory portion available by addressing it beyond the MB.
This memory remapping function also includes a Shadow RAM function that allows BIOS ROM to
be recopied by the system into the system memory at the same logic address locations in order to
speed up the system.
These operation generates adjacent physical address space (physical memory map) from which a
logic address space can be configured, these logic addresses may be not adjacent (logic memory
map). In this case, for instance, it is possible to intercalate portions of memory resident on boards installed on BUS with portions of memory of system board.
LIMITATIONS FOR MEMORY CONFIGURATION
There are some limitations when using these system memory configuration function.
Limitations are as follows:
AT Compatibility Gap - system needs this GAP
External memory can not be mapped in the logic address area reserved for this gap (0A000h to
0FFFFF h).
128 KB memory segment size - this function works only for memory segments of 128 KB.
The first 258 KB is always used by system internal memory - this 256 KB is reserved for BIOS
during Power-On procedure. This memory space requires that the physical address be equal to
logic address. This means that the first two memory segments of 128 KB must belong to system
memory.
If these limitations are violated, automatically the system gives priority to physical memory map, ignoring the logic memory map. As a result, the external memory installed is ignored.
Another case is to be taken into consideration: when the maximum memory is installed, i.e.
16 MB.
In this case there is logic addressing space to remap the AT compatibility Gap which, therefore, will
be a usual read/write RAM memory. In this situation, the user memory available depends on how
the Shadow RAM option is used.
Shadow RAM disabled
512 KB of AT compatibility Gap is ignored by the system and is lost.
System total memory is therefore 15.872 KB (16.384 - 512 = 15.872).
Therefore, system looses 512 KB.
Only video BIOS in shadow RAM
64 KB of AT compatibility gap is recovered because it is remapped.
64 KB of video BIOS are set in shadow RAM. System total memory is therefore is 16.000 KB
(16.384 - 512 + 64 recovered +64 in shadow = 16.000).
Therefore, system looses 384 KB.
System BIOS and video BIOS in shadow RAM
32 KB of AT compatibility gap is recovered because it is remapped. 96 KB of system BIOS and
video BIOS are set in shadow RAM. System total memory, therefore, is 16.000
(16.384 - 512 + 32 recovered + 96 in shadow = 16.000). Therefore, system loses 384 KB.

SYSTEM MEMORY MAP
AT standard has a basic memory of 512 KB, expandable up to 640 KB, in which remapping of physical memory areas is not requested.
With a basic memory expansion beyond 640 KB, a logic addressing conflict arises because the
physical memory between 640 KB and 1 MB occupies the logic addressing space reserved for
ROM BIOS addressing. This addressing space between 640 KB and 1 MB is called AT compatibility gap.
In order not to lose this memory space, in these systems a remapping function has been introduced
which makes it possible to have this memory portion available by addressing it beyond the MB.
This memory remapping function also includes a Shadow RAM function that allows ROM BIOS to
be recopied by the system into the system memory at the same logic address locations in order to
speed up the system.
These operation generates adjacent physical address space (physical memory map) from which a
logic address space can be configured, these logic addresses may be not adjacent (logic memory
map). In this case, for instance, it is possible to intercalate portions of memory resident on boards installed on the BUS with portions of memory of system board.
LIMITATIONS FOR MEMORY CONFIGURATION
There are some limitations when using these system memory configuration function.
Limitations are as follows:
AT Compatibility Gap - system needs this GAP
External memory can not be mapped in the logic address area reserved for this gap (0A000h to
0FFFFF h).
128 KB memory segment size - this function works only for memory segments of 128 KB.
The first 258 KB is always used by system internal memory - this 256 KB is reserved for BIOS
during Power-On procedure. This memory space requires that the physical address be equal to
logic address. This means that the first two memory segments of 128 KB must belong to system
memory.
If these limitations are violated, automatically the system gives priority to physical memory map, ignoring the logic memory map. As a result, the external memory installed is ignored.
Another case is to be taken into consideration: when the maximum memory is installed,
i.e. 16 MB.
In this case there is logic addressing space to remap the AT compatibility Gap which, therefore, will
be a usual read/write RAM memory. In this situation, the user memory available depends on how
the Shadow RAM option is used.
Shadow RAM disabled
512 KB of AT compatibility Gap is ignored by the system and is lost.
System total memory is therefore 15.872 KB (16.384 - 512 = 15.872).
Therefore, system loses 512 KB.
Only video BIOS in shadow RAM
64 KB of AT compatibility gap is recovered because it is remapped.
64 KB of video BIOS is set in shadow RAM. System total memory is therefore is 16.000 KB
(16.384 - 512 + 64 recovered +64 in shadow = 16.000).
Therefore, system loses 384 KB.
System BIOS and video BIOS in shadow RAM
32 KB of AT compatibility gap is recovered because it is remapped. 96 KB of system BIOS and
video BIOS is set in shadow RAM. System total memory, therefore, is 16.000
(16.384 - 512 + 32 recovered + 96 in shadow = 16.000).
Therefore, system loses 384 KB.

SYSTEM MEMORY MAP
AT standard has a basic memory of 512 KB, expandable up to 640 KB, in which remapping of physical memory areas is not requested.
With a basic memory expansion beyond 640 KB, a logic addressing conflict arises because the
physical memory between 640 KB and 1 MB occupies the logic addressing space reserved for
ROM BIOS addressing. This addressing space between 640 KB and 1 MB is called AT compatibility gap.
In order not to lose this memory space, in these systems a remapping function has been introduced
which makes it possible to have this memory portion available by addressing it beyond the MB.
This memory remapping function also includes a Shadow RAM function that allows ROM BIOS to
be recopied by the system into the system memory at the same logic address locations in order to
speed up the system.
These operation generates adjacent physical address space (physical memory map) from which a
logic address space can be configured, these logic addresses may be not adjacent (logic memory
map). In this case, for instance, it is possible to intercalate portions of memory resident on boards
installed on the BUS with portions of memory of system board.
LIMITATIONS FOR MEMORY CONFIGURATION
There are some limitations when using these system memory configuration function.
Limitations are as follows:
AT Compatibility Gap - system needs this GAP
External memory can not be mapped in the logic address area reserved for this gap
(0A000h to 0FFFFF h).
128 KB memory segment size - works only for 128 KB memory segments.
The first 258 KB is always used by system internal memory - this 256 KB is reserved for BIOS
during Power-On procedure. This memory space requires that the physical address be equal to
logic address. This means that the first two memory segments of 128 KB must belong to system
memory.
If these limitations are violated, automatically the system gives priority to physical memory map,
ignoring the logic memory map. As a result, the external memory installed is ignored.
Another case is to be taken into consideration: when the maximum memory is installed,
i.e. 16 MB.
In this case there is logic addressing space to remap the AT compatibility Gap which, therefore, will
be a usual read/write RAM memory. In this situation, the user memory available depends on how
the Shadow RAM option is used.
Shadow RAM disabled
512 KB of AT compatibility Gap is ignored by the system and is lost.
System total memory is therefore 15.872 KB (16.384 - 512 = 15.872).
Therefore the system loses 512 KB.
20
Only video BIOS in shadow RAM
64 KB of AT compatibility gap is recovered because it is remapped.
64 KB of video BIOS is set in shadow RAM. System total memory is therefore is 16.000 KB (16.384
- 512 + 64 recovered +64 in shadow = 16.000).
Therefore the system loses 384 KB.
System BIOS and video BIOS in shadow RAM
32 KB of AT compatibility gap is recovered because it is remapped. 96 KB of system BIOS and
video BIOS is set in shadow RAM. System total memory, therefore, is 16.000 (16.384 - 512 + 32 recovered + 96 in shadow = 16.000).
Therefore the system loses 384 KB.

COMPATIBILITY
Streaming tape with floppy
disk interface
The software for streaming tape unit management may enter into
conflict with the floppy disk controller when the latter is
programmed for operation in "perpendicular - mode" (programming
for 2.88 MB floppy disks). BIOS 1.07 solves this problem.
In any case, it is possible to use this streaming tape by jumpering it
in position ID 4 to avoid the programming conflict between the
EZTAPE management program and the floppy disk controller.

board with PCB BA301
Replacement of motherboard PCB BA901 with PCB
BA 301 may result in problems with the management of 340 MB
hard disks. When changing board the hard disk should be
reformatted (low level format). If this is not possible, because the
hard disk contains data that cannot be lost, it is still possible to use
it with the new system board by configuring it as a non- standard
hard disk and giving the following parameters:
HDU 340 MB Conner CP3304
Cyl. = 726
Land. zone = 726
Auxiliary = 112
Heads = 15 Sectors = 61

- Automatic HDU acknowledgement selecting the "standard" function which will
be included in the user diskette release 2.02.
- Management of the new VESA 72.8 Hz monitors.
- Management of 2.88 MB drives
Rev. 2.01
This release has the following variations with respect to the previous one:
- Change at Security level so that the Power-On password is copied on the
Keyboard password, only when there is a Power-On and not when there is a
Soft-reset (Ctrl-Alt-Del) or a Jump to F000:FFF0.
Banner change for introduction of the new type P24 50/66 MHz CPU
- The "ROM checksum error" error on rebooting after the SETUP has been
removed.
- Various faults concerning new HDU management have been corrected.
- New corrections made to 2.88 MB floppy drive management.
- A new video table has been introduced for the 11h,12h,79h 72Hz modes due to
VESA.N.B. timing problems.
This release does not yet implement the the facility by which the user has the
possibility of setting non-standard hard disks and presents faults on HDUs
when working in Shadow disabled mode (condition not much used).
Rev. 2.02
Corrected the faults with the OLICOM
"V24 LPU 2100/2400/3500/3600" board.
Rev. 2.03

Some corrections made in management of 2.88 MB floppy disks.
Some system faults with Shadow memory disabled have been corrected.
Problems concerning management of non-standard Hard Disks with high
capacity (600 MB) have been solved.
Rev. 2.05
This release has the following variations with respect to the previous release:
- Corrected message conecrning CPU type 486DX2.
- Corrected message concerning Dedicated memory when disabling the memory
between 512K and 640K and performing a controlled reset.
- Corrected malfunctioning of the interrupt controller and refresh tests caused by
the increase in clock frequency of the computer (486DX2 for M400-60).
- Correction to eliminate malfunctioning of the floppy disk running Windows 3.0 in
standard mode.
Windows release 3.1 does not have this problem.
- Change made for management of the 6K between C680 and C7FF as ROM
option.
This BIOS revision is also extended to the M400-60 personal computer so
subsequent issues of the BIOS will be attributed to all systems of the M400-10,
M400- 40 and M400-60 family.
Rev. 2.06
This release corrects the following:
- Bootstrapping delays with CP3304 HDUs and other MASTER HDUs
- Spurious characters when a password is typed using slow keyboards
- Cache for compatibility with COMPUTONE AT 8/16 boards
- Cancelled the hidden partitions message displayed after the POD

HARD DISK SELF-ACKNOWLEDGEMENT FEATURE
M400-10 systems with motherboard BA312 or BA313 have the hard disk self-acknowledgement feature. This feature is not included on BA926 and BA927, which still have the BUILT IN SETUP utility.
Using the SETUP utility of the System Test or Customer Test, the type of hard disk installed in the
system can be defined. Having selected the SETUP utility, select the option hard disk #1 and #2.
The following values can be defined in this field:
Not Present:
If no hard disk is installed.
Standard
In this case the system automatically acknowledges type and capacity of the
hard disk installed. This option can be used for hard disks including the selfacknowedlge device and have capacity of less than 528 MB.
High Capacity
In this case, the system automatically acknowledges type and capacity of the
hard disk installed. This option must be used for hard disks with a capacity of
more than 528 with the self-acknowledge device and which are to be used with
the Olivetti OS/2, IBM OS/2 and MS-DOS operating systems.
Compatible
This option must be used for hard disks compatible with the system but which
do not have the self-acknowledge device, or hard disks which do have this
feature but which have previously been used on other systems. If this option is
chosen, a list of hard disks with preset parameters will be displayed. Check that
the parameters defined match with those on the label of the hard disk being
installed. The types of hard disk are as follows:

BIOS EVOLUTION
LEVEL
EVOLUTION
Rev. 2.00
This release introduces the following features:
- Automatic HDU acknowledgement selecting the "standard" function which will
be included in the user diskette release 2.02.
- Management of the new VESA 72.8 Hz monitors.
- Management of 2.88 MB drives
Rev. 2.01
This release has the following variations with respect to the previous:
- Change at Security level so that the Power-On password is copied on the
Keyboard password, only when there is a Power-On and not when there is a
Soft-reset (Ctrl-Alt-Del) or a Jump to F000:FFF0.
Banner change for introduction of the new P24 50/66 MHz CPUs
- The "ROM checksum error" error on rebooting after the setup has been
removed.
- Various malfunctionings concerning new HDU management have been
corrected.
- New corrections made to 2.88 MB floppy drive management.
- A new video table has been introduced for the 11h,12h,79h 72Hz modes due to
VESA.N.B. timing problems.
This release does not yet implement the facility by which the user has the possibility
of setting non-standard hard disks and presents HDU faults when working with a
disabled shadow (condition not much used).
Rev. 2.02
Corrected the fault with the OLICOM "V24 LPU 2100/2400/3500/3600" board.
Rev. 2.03
Corrected the "Memory Refresh Error" appearing randomly after a Ctrl-Alt-Del reset.
Rev. 2.04
-
Corrected the "Keyboard Error" appearing randomly during the POD
after a Ctrl-Alt-Del.
Corrected problem of failure to Bootstrap from floppy disk when a HD
previously installed on other systems is disconnected.
Some corrections made in management of 2.88 MB floppy disks.
Some malfunctionings of the computer with the Shadow memory disabled have
been corrected.
Problems concerning management of non-standard Hard Disks with high
capacity (600 MB) have been solved.
Rev. 2.05
THis release has the following variations with respect to the previous release:
- Corrected message concerning CPU type 486DX2.
- Corrected message concerning Dedicated memory when disabling the memory
between 512K and 640K and performing a controlled reset.
- Corrected malfunctioning of the interrupt controller and refresh tests caused by
the increase in clock frequency of the computer (486DX2 for M400-60).
- Correction to eliminate malfunctioning of the floppy disk running Windows 3.0 in
standard mode.
Windows release 3.1 does not have this problem.
- Change made for management of the 6K between C680 and C7FF as ROM
option.
This BIOS revision is also extended to the M400-60 personal computer so
subsequent BIOS issues will be attributed to all systems of the M400-10, M400-40
and M400-60 family.
Rev. 2.06
This release corrects the following:
- Bootstrapping delays with CP3304 HDUs or other MASTER HDUs
- Spurious characters when the password is entered on slow keyboards
- Cache for compatibility with COMPUTONE AT 8/16 boards
- Cancelled the message at the end of the POD indicating hidden partitions
Rev. 2.08
Corrected the problem with IBM OS/2 ver. 2.0 in a DOS window.

HARD DISK SELF-ACKNOWLEDGE FEATURE
This system have the hard disk self-acknowledge feature.
Using the SETUP utility of the System Test or Customer Test, the type of hard disk installed in the
system can be defined. Having selected the SETUP utility, select the option hard disk #1 and #2.
The following values can be defined in this field:
Not Present:
If no hard disk is installed.
Standard
In this case the system automatically acknowledges type and capacity of the
hard disk installed. This option can be used for hard disks including the selfacknowedlge device and have capacity of less than 528 MB.
High Capacity
In this case, the system automatically acknowledges type and capacity of the
hard disk installed. This option must be used for hard disks with a capacity of
more than 528 with the self-acknowledge device and which are to be used with
the Olivetti OS/2, IBM OS/2 and MS-DOS operating systems.
Compatible
This option must be used for hard disks compatible with the system but which
do not have the self- acknowledge device, or hard disks which do have this
feature but which have previously been used on other systems. If this option is
chosen, a list of hard disks with preset parameters will be displayed. Check that
the parameters defined match with those on the label of the hard disk being
installed. The following table lists these hard disks:

HARD DISK SELF-ACKNOWLEGE FEATURE
This system has the hard disk slef-acknowledge feature.
Using the SETUP utility of the System Test or Customer Test, it is possible to define the type of
hard disk installed in the system. After the SETUP utility has been selected, select option hard disk
#1 and #2. The following values can be defined in this field:
Not Present:
Where no hard disk is installed.
Standard
In this case, the system automatically acknowledges type and capacity of the
hard disk installed. This option can be used for hard disks with the selfacknowledge feature and with a capacity of less than 528 MB.
High Capacity
In this case, the system automatically acknowledges type and capacity of the
hard disk installed. This option must be used for hard disks with a capacity of
more than 528 MB with the self-acknowledge feature and which have to be
used with the Olivetti OS/2, IBM OS/2 and MS-DOS operating systems.
Compatible
This option must be used for hard disks that are compatible with the system but
which do not have the self-acknowledge feature, or hard disks that do have the
feature but which have been used before hand on systems other than this one.
When this option is selected, a list is displayed of the hard disks with preset
parameters. Check that the parameters defined match those of the hard disk
being installed. The different types are illustrated in the table below:

LEVEL
NOTES
Rev. 1.00
This BIOS release can only be installed on systems with BA317 or BA302
updated to the same level.
Rev. 1.01
This release removes some bugs on the previous release and solves:
- Problems with the KP.EXE utility in the CUSTOMER DISK Rev. 1.00
- Problems with the GOSLOW/AUTOSLOW utility. For correct use of the
GOSLOW/GOFAST features, updating is also required of the utilities of the
CUSTOMER DISK as those present in release Rev.1.00 do not work
Rev. 1.03
This release removes some bugs on the previous BIOS release (Rev. 1.02)
- Video modes 72h and 79h have been removed
- Problems with Windows 3 Video Mode 53h at 72Hz
- Problems in enabling the high resolution
BIOS Rev. 1.03 supports the non-standard HDU feature activated from the USER
DISK. This change has also entailed a change in the tables of HDU parameters
integrated in the BIOS. The hard disks with the self-acknowledge feature have
been eliminated from the hard disk tables (see the following tables).
Rev. 1.04
This BIOS release is identical to the previous BIOS as regards the system BIOS
code part. As for the video BIOS, an adjustment has been made to programming
of the FIFO on the video controller of the OAK, so as to improve use depending on
the video modes selected.
Rev. 1.05
This BIOS release solves problems arising in the previous versions:
- Incorrect initialization of the VGA AST board during POD
- Keyboard interrupt management.
- Bug on procedures for buzzer volume management
- With shadow RAM disabled, the system does not configure correctly if the
BUS is particularly full.
- Management of the video test error code.
- System crash following a Soft Reset with the video off.
Rev. 1.06
This BIOS release solves critical problems of the POD arising in the previous
version.
Rev. 1.07
During the POD, the DOC clock in the BIOS DATA AREA is initialized, before
relinquishing control to any ROM options installed in the system

HARD DISK SELF-ACKNOWLEDGE FEATURE
The M300-08 system has the hard disk self-acknowledge feature.
Using the BUILT IN SETUP or the SET UP utility of the System Test or Customer Test, it is
possible to define the type of hard disk installed in the system.
BUILT IN SETUP
The BUILT IN SETUP offers a number of options:
AUTO
28
This option is for installation of a hard disk with the self-acknowledge feature.

bringing to these systems a disk formatted on an "earlier system", keeping that data that was
recorded on it.
If the hard disk is new, the self-acknowledge feature can be used.
A new hard disk table has been implemented in subsequent BIOS versions.

SYSTEM TEST - CUSTOMER TEST
Having selected the SETUP utility of the Customer Test or System Test, select the option hard disk
#1 and #2. The following values can be defined in this field:
Not Present
If no hard disk is installed
Standard
In this case the system automatically acknowledges type and capacity of the
hard disk installed.
This option can be used for hard disks that have the self-acknowledge feature
and have a capacity of less than 526 MB.
High Capacity
In this case the system automatically acknowledges type and capacity of the
hard disk installed. This option must be used for hard disks with a capacity of
more than 526 MB with the self-acknowledge feature and which have to be used
with operating systems Olivetti OS/2IBM OS/2 and MS-DOS.
Compatible
This is the option to be used for hard disks that are compatible with the system
but do not have the self-acknowledge feature. If this option is selected, a list will
be displayed of hard disks with preset parameters (see the BUILT IN SETUP
table).
Check that the parameter preset values correspond to those on the label of the
hard disk being installed.
Not Standard
This option allows the service engineer to personally define the parameters of a
hard disk without the self-acknowledge feature and which is not included in the
list of compatible hard disks.
SHADOW MEMORY FEATURE AND MEMORY REMAPPING
These are utilities that can be selected from the Customer Test or System Test
Shadow memory feature:
For faster system BIOS access. The ROM BIOS code is copied to the same logic addresses into
the system RAM (Shadow RAM).
It is possible to select which part of the BIOS code to copy into Shadow RAM:
Only the 64 KB system BIOS
C000
E800
Only the 32 KB vIdeo BIOS
Only the 32 KB video BIOS
System BIOS and video BIOS
The posibility of copying the video BIOS to two different addresses derives from the fact that some
boards use segment C000 to run their functions (the MATROX video controller, for instance) and as
this result this segment cannot be used to copy the video BIOS into.

During the POD, the DOC clock in the BIOS DATA AREA is initialized before
control is relinquishedp to any ROM option installed in the system.
HARD DISK SELF-ACKNOWLEDGE
The M300-15 has the the hard disk self-acknowledge feature.
Through the BUILT IN SETUP or the SET UP utility of the System Test or Customer Test, the type
of hard disk installed in the system can be defined.
For information on this feature, see the previous chapter on the M300-08.
SHADOW MEMORY FEATURE AND MEMORY REMAPPING
These are utilities that can be selected from the Customer Test or the System Test.

FRONT BAYS FOR MAGNETIC AND OPTICAL PERIPHERALS
The M480-40 mechanical structure has 10 half-height, 5.25" bays. These base are subject to the following limitations of use:
-
Bay 10 (highest) is always used for a 3.5" floppy disk
Bay 1 (lowest) is always used for the first hard disk of the system
Bays 9 to 5 can accomodate removible magnetic peripherals. The number of removible SCSI
peripherals is confined to 2.
Bays 7 to 5 can also accomodate SCSI hard disks
Bays 4 to 1 must only accomodate SCSI hard disks.
The floppy disk interface peripherals
must be installed in the first three
bays (10, 9, 8).
CONSOLE
All the SCSI peripherals must be
installed in the next bays starting from
bay 7.
BAY 10
FDU 1.44 MB 3.5" or
FDU 2.88 MB 3.5"

SCSI CHANNEL CONFIGURATION
The general rule in configuring the SCSI channel is that all the devices connected (at most 8, SCSI
controller included) have a different SCSI ID and that the BUS is terminated at one end only.
-
-
The SCSI ID as well as assigning a different address to each peripheral also ests the priority.
SCSI ID 7 is the highest priority and SCSI ID 0 the lowest.
In the M480-40, the first hard disk installed must have SCSI ID 6 and must be installed in bay 1.
The SCSI controller has SCSI ID 7.
The other SCSI peripherals must be given decreasing SCSI IDs as they are installed.
A disk pack, consisting of 2 hard disks, must be given two SCSI IDs.
The primary SCSI contoller must be installed in MCA slot 1. If there are several SCSI controllers
in the system, then first hard disk, which must have a part of the BIOS, must be connected with
the SCSI controller installed in MCA slot 1 and have an SCSI ID of 6.
The SCSI ID on each peripheral is configured through jumpers on the board.
The SCSI ID of the SCSI controller is configured through the software using the User Diskette or
System Test.
Termination rules
If there are no external SCSI devices, the hard disk or primary disk pack in bay 1 and the SCSI controller must always be terminated. If there are SCSI peripherals connected outside of the system
module, the terminator must be removed from the SCSI controller and the last external peripheral
connected to the system must be terminated.
WIRING OF PERIPHERALS
The following figures illustrate wiring of the floppy interface peripherals and of the SCSI interface peripherals.
Wiring of floppy disk interface peripherals
To manage the different interface signals bewteen the floppy disks, the floppy disk cable has two
connectors for each of the peripherals that it is possible to install. The bottom connector of each
pair must be used when installing a 1.44 MB, 1.2 MB floppy disk or streaming tape. The upper connector must be used when installing a 2.88 MB floppy disk.

Wiring of SCSI interface peripherals
The SCSI cable is a straight cable connecting at one end to the SCSI hard disk controller and with
3 connectors at the oter end for connection of the peripherals. The last connector must be used to
connect the first hard disk of the system, whereas the other two must be used to connect SCSI
removable type peripherals.
To add a hard disk, you must:
1. Insert it in the bay immediately above the one already occupied
2. Disconnect the connector connected to the hard disk already installed and connect it to the hard
disk being added.
3. Between the hard disk being added and the one already installed, connect the extension cable
included in the installation kit of the hard disk option being added

FRONT BAYS FOR MAGNETIC AND OPTICAL PERIPHERALS
The mechanical structure of the M480-60 has 10 5.25" half-height bays. These bays are subject to
the following limitations of use:
-
Bay 10 (highest) is always used to accomodate a 3.5" floppy disk drive
Bay 1 (lowest) is always used to accomodate the system’s first hard disk drive
Bays 9 to 5 can accomodate removabile peripherals. A maximum of 2 removable
SCSI peripherals can be installed
Bays 7 to 5 can also accomodate SCSI hard disk drives
Bays 4 to 1 must only accomodate SCSI hard disk drives.
The peripherals with a floppy disk
interface must be installed in the first
three bays (10, 9 and 8).
CONSOLE
All SCSI peripherals must be installed
in the next bays starting from bay 7.
BAY 10
3.5" 1.44 MB FDU or
3.5" 2.88 MB FDU
The removable peripherals (floppy disk,
streaming tape, CD-ROM, DAT) must
be installed in the high bays.
The fixed disk peripherals must be
installed in the low bays.

SCSI CHANNEL CONFIGURATION
The general rule for configuring the SCSI channel is that all the devices connected (up to 8, including the SCSI controller) have to have a different identifier (SCSI ID) and the BUS must be
terminated at both ends only.
- The SCSI ID, in addition to assigning a different address to each peripheral, determines also the
priority. SCSI ID 7 is the highest priority, SCSI ID 0 the lowest.
- The first hard disk installed on the M480-60 must have SCSI ID 6 and must be installed in bay 1.
The SCSI controller has SCSI ID 7.
- The other SCSI peripherals must be given decreasing SCSI IDs as they are installed.
- The disk pack, consisting of 2 hard disks, must be given two SCSi IDs.
- The primary SCSI controller must be installed in MCA slot 1. If there are several SCSI controllers
in the system, the first hard disk, which must contain part of the BIOS, must be connected with
31
the SCSI controller installed in MCA slot 1and have a SCSI ID of 6.
- On each peripheral, the SCSI ID must be set through the jumpers on the peripheral itself.
The SCSI ID of the SCSI controller is configured via software using the User Diskette or the
Customer Test.
Termination rules
If there are no external SCSI peripherals, the hard disk or primary disk pack in bay 1 and the SCSI
controller must always be terminated. If there are external SCSI peripherals connected to the basic
module, the terminator must be removed from the SCSI controller and the last external peripheral
connected to the system must be terminated.
WIRING OF PERIPHERALS
The following figures show the wiring of the peripherals with floppy interface and those with SCSI interface.
Wiring of peripheral with floppy disk interface
In order to manage the different interface signals between the floppy disks, the floppy disk cable
has two connectors for each of the peripherals that can be installed. The bottom connector of each
pair of must be used when installing 1.44 MB, 1.2 MB or streaming tape drives. The upper connector must be used when installing a 2.88 MB floppy disk drive.

Personal Computer - Pocket Service Guide
Wiring of peripherals with SCSI interface
The SCSI cable is a straight cable connecting at one end to the SCSI hard disk controller and with
three connectors at the other end connecting to the peripherals. The last connector must be connected to the system’s first hard disk, while the other two must be connected to removable SCSI
peripherals.
To add a hard disk, proceed as follows:
1. Insert the hard disk in the bay immediately above the one already occupied.
2. Disconnect the connector attached to the hard disk already installed and attach it to the hard
disk being added.
3. Between the hard disk being added and the one already installed, connect the extension cable
provided in the installation kit of the hard disk option being added.

BUILT IN SETUP and EXTENDED SETUP Utilities
BUILT IN SETUP
This program, resident in ROM BIOS, allows users to change some of the Personal Computer configuration parameters.
There are two possibilities:
First case: If the information in the CMOS RAM is no longer valid or if the power battery is not charging, the screen will display the BUILT IN SETUP. Users can select the national language version
they wish to work in from a choice of 6 languages.
Second case: If the system configuration has been modified, only the icon of the device to be
added or changed in the CMOS RAM will be displayed. For instance, after installing a second
floppy disk the floppy disk icon will be displayed.
In both cases, this BUILT IN SETUP screen will be displayed automatically, without any operator ac- 32
tion.
F1 To modify hour, minutes and seconds.
F2 To modify day, month and year.
F3 Press this key to select hard disk type and capacity. Press the space bar until the correct value is
displayed. The following table lists the hard disks that can be installed in this system.

F4 Press this key to select capacity of the floppy disk.Three fields will be displayed beside the icon,
according to the number of drives (1, 2 or 3) in the system; enter the capacity of the floppy disk
installed in the corresponding field.
The line underneath shows the letters A (for one drive only), A - B (for two drives) or
A - B - X (for three drives). These are the logic names of the drives.
NOTE:
To install a floppy interface streaming tape, the data field corresponding to this
unit must not contain any value and the drive must have logic name B associated
with it.
F5 Press this key to select video format when the system is switched on.
Memory
The information in this field cannot be changed since its only purpose is to
inform the user of system memory capacity. The System or Customer
Test diskette will be needed if you wish to change system memory size.
Numeric coprocessor
This icon is displayed only when the WEITEK coprocessor is installed and
is for the information of the user only.
Batteries
This icon is displayed only when the system is switched on for the
first time or when the system batteries are not charging.
Real time clock
This icon blinks when there is a failure of the system’s
Real Time Clock .
Language
It is possible to select the language in which to have the messages of
the BUILT IN SETUP displayed. There are six languages to choose from.

BUILT IN SETUP and EXTENDED SETUP Utilities
BUILT IN SETUP
This program, resident in ROM BIOS, allows users to change some of the Personal Computer configuration parameters.
There are two possibilities:
First case: If the information in the CMOS RAM is no longer valid or if the power battery is not charging, the screen will display the BUILT IN SETUP. Users can select the national language version
they wish to work in from a choice of 6 languages.
Second case: If the system configuration has been modified, only the icon of the device to be
added or changed in the CMOS RAM will be displayed. For instance, after installing a second
floppy disk the floppy disk icon will be displayed.
In both cases, this BUILT IN SETUP screen will be displayed automatically, without any operator
action.
F1 To modify the system hour, minutes and seconds.
F2 To modify the system day, month and year.
F3 Press this key to select hard disk type and capacity. Press the space bar until the correct value is
displayed. The following table lists the hard disks that can eb installed in the system.

BUILT IN SETUP and EXTENDED SETUP Utilities
The M480-10 and M480-20 personal computers with BIOS release 2.xx no longer use the BUILT IN
SETUP utility, and can be configured using the User Diskette or System Test.
BUILT IN SETUP
This program, resident in the ROM BIOS, allows users to change some of the Personal Computer
configuration parameters.
There are two possibilities:
First case: If the information in the CMOS RAM is no longer valid or if the power battery is not charging, the screen will display the BUILT IN SETUP. Users can select the national language version
they wish to work in from a choice of 6 languages.
Second case: If the system configuration has been modified, only the icon of the device to be
added or changed in the CMOS RAM will be displayed. For instance, after installing a second
floppy disk the floppy disk icon will be displayed. In both cases, this BUILT IN SETUP screen will be
displayed automatically, without any operator action.
F1
To modify the system hour, minutes and seconds.
F2
To modify the system day, month and year.
F3
Press this key to select hard disk type and capacity. Press the space bar until the correct
value is displayed. The following table lists the hard disks that can be installed in the system.

according to the number of drives (1, 2 or 3) in the system; enter the capacity of the floppy disk
drive installed in the corresponding field.
The line underneath shows the letters A (for one drive only), A - B (for two drives) or A - B - X
(for three drives). These are the logic names of the drives.
NOTE:
To install a streaming tape drive with floppy interface, the data field corresponding
to this unit must not contain any value and the drive must have logic name B
associated with it.

HARD DISK SELF-ACKNOWLEGE FEATURE
The hard disk self-acknowledge feature is available on systems with BIOS revision 2.xx .
Using the SETUP utility of the System Test or Customer Test, it is possible to define the type of
hard disk installed in the system. After the SETUP utility has been selected, select option hard disk
#1 and #2. The following values can be defined in this field:
Not Present:
Where no hard disk is installed.
Standard
In this case, the system automatically acknowledges type and capacity of the
hard disk installed. This option can be used for hard disks with the selfacknowledge feature and with a capacity of less than 528 MB.
High Capacity
In this case, the system automatically acknowledges type and capacity of the
hard disk installed. This option must be used for hard disks with a capacity of
more than 528 MB with the self-acknowledge feature and which have to be
used with the Olivetti OS/2, IBM OS/2 and MS-DOS operating systems.
Compatible
This option must be used for hard disks that are compatible with the system but
which do not have the self-acknowledge feature, or hard disks that do have the
feature but which have been used before hand on systems other than this one.
When this option is selected, a list is displayed of the hard disks with preset
parameters. Check that the parameters defined match those of the hard disk
being installed. The different types are illustrated in the table below:

This option allows the service engineer to personally define the parameters of a
hard disk without the self-acknowledge feature and which are not in the list of
compatible hard disks. The table listing the parameters of the hard disks that are
supported by the system BIOS is the same as that of the M400-40 Personal

BUILT IN SETUP
During the Power On Diagnostics, the following message is displayed after checkpoint 2ch:
“PRESS CTRL-ALT- ESC for SETUP”
From now until the moment the BIOS begins the system bootstrapping sequence, you will have the
possibility of accessing the system SETUP facility. When SETUP is requested, the software reads
the contents of CMOS RAM. If the CMOS is altered, default values will be used.
If, when exiting SETUP, you decide to save the modifications made, the program will copy the new
configuration into CMOS and calculate the new checksum.
The SETUP utility consists of four screens that directly interface the system BIOS, and is displayed
in English only.
The first screen is only informative. The information collected during the first part of the POD is displayed on the left-hand side of this screen, while the different icons that give access to the other
screens are displayed on the right-hand side.
The SETUP utility has usual interface with pop-up menus. The following function keys can be used:
arrow keys, the <ENTER> key, the F2 key to switch from between a color and monochrome interface, the F10 or <ESC> key to move upwards from one screen to another until reaching the very
first menu screen with the EXIT icon.
SYSTEM CONFIGURATION
This is the first screen of the SETUP utility; the values that appear in the individual fields are specific for each machine configuration. The icons that give access to the different screens are
displayed on the right-hand side of the screen:

1st MENU - SYSTEM SETUP
This is the first menu of the SETUP utility. A help window is displayed on the right-hand side of the
screen. Each time you select a SETUP parameter, this window will display the meaning of this parameter and how to use it.
System Date:
System Time:
Allows you to enter or change the system date according to the following
format: mm/dd/yy.
Allows you to enter or change the system time.
Floppy diskette 1:
Floppy diskette 2: Allows you to define the type of floppy disk drive installed in the system.
Drive 1 is the default drive. The following drives can be defined: NONE, 360K,
1.2M, 720K, 1.4M.

Video:
Allows you to select the type of monitor connected to the system. The following can
be defined: Mono, EGA/VGA, Color 40, Color 80.
Mouse Port: Allows you to enable or disable the mouse port. If Enabled is defined but the mouse
port is not detected, this parameter will automatically change to Disabled.
Processor Speed:
Allows you to set the processor speed so that the system becomes
compatible with the previous generation of slower microprocessors.
The values that can be defined are Fast and Slow.
Video VDU Refresh Rate: Allows you to select the video refresh rate. The following values can
be defined: 60 Hz and 72 Hz.
Hard Disk Table
The hard disk table is an area of the BIOS that stores operating characteristics of a rappresentative
group of hard disk drives. The information does not refer to a specific manufacturer but to the
characteristics of the standard drives available.
Each table entry is identified by a specific type, and there are 47 predefined types of drives listed.
The last two types, 48 and 49, can provide the values obtained by the self-acknowledge feature of
the first or second (not expected) hard disk drive installed in the system.
WARNING:
Since the BIOS supports the hard disk self-acknowledge feature, the Disk
parameter is usually configured automatically. This is because the intelligent hard
disk drive (IDE interface) provides its own configuration parameters (Capacity,
Cylinders, Heads, Sectors, Precompensation and Head Landing Zone) to the BIOS.
The self-configured disk is identified as Type 48.

New printed circuit wirings.
100 Ohm resistances R521, R522 have been
changed to 200 Ohm. This modification solves
the problem with background colors when using
Windows 3.1.
NOTE: Only the value of resistance R522 must be
modified in field (which actually solves the
problem), and not the value of R521 (which
improves the functional margins only).
Lev. 02 MI
Modified the value of the following resistances:
R527, R528 from 100 Ohm to 470 Ohm
R426 from 180 Ohm to 100 Ohm
These modifications were made to solve random
video memory errors. This problem occurs only on
boards using a certain type of buffer:
Motorola F244 xxAE9302 and Texas F244.

New keyboard controller Rev. 10.02 to replace
Rev. 10.01.
This new controller is available in two versions:
OPT (function name CSKM) or
ROM (function name CSKL). The modification
solves the problems with the mouse and relative
driver being too slow for the speed of the
66 MHz i886 DX2.
- The following components are mounted on the
board:
Transistor 2N3904
Resistances R478 and R477
This solves the problem of the system
crashing when the 386MAX software is used.
NOTE: This problem can also be solved via

To solve the parity errors during a DMA cycle
when using two Adaptec SCSI boards and one
communication board installed in the last slot of
the expansion bus, a 100pF capacitor is
installed between pin 1 and GND of component
U19.
To cut costs, some capacitors have been
replaced.
A new ATI 68800-6 video controller replaces the

- Management of disk A disable security feature during a bootstrap routine
in the system region environment. This problem occurred whenever the
bootstrap routine was launched from the system region where the system
Setup program is stored, and the bootstrap for disk A security feature is
selected. In this case the message "No system disk" was displayed and
you were asked to press a key which would have launched the bootstrap
routine from the system region. This modification ensures that bootstrapping
is performed automatically.
Rev. 1.10
Solves the following problems of release 1.09:
- Possibility of disabling the second serial port through Setup.
- Possibility of configuring the I/O address of the primary parallel port through
Setup.
- Cache controller enable before the the bootstrap interrupt to solve the problems
with boards using the optional ROM. When installed on the bus, these boards
would replace the system BIOS bootstrap interrupt with one of their own, thus
degrading their own performance
- Management of the TI 68800-AX-6 video controller.
Rev. 1.11
Introduces a 50 MHz clock. Can also handle the Norway keyboard.
Rev. 1.13
This revision allows True Color video mode management. This BIOS revision
was never produced.
Rev. 1.14
Corrects the problem with some videos which automatically switch to black and
white mode after a software reset.
Rev. 1.16
This BIOS release solves the following problems:
- Distinguishes the 486 CPU from the 486SX2 CPU during system bootstrap
- Correctly handles the ETHERLINK 16 3C507 line board
- Handles the Siemens SIMMs
- Handles the second level of Chips and Technology’s 4021 chipset
- Handles hard disks with timing problems, in particular CONNER 85 MB and
170 MB drives.
Rev. 1.18
This revision allows the management of memory between 512 KB and 1 MB with
the second level of chipset CS4021.
It also corrects the ATI 68800 (Setp 6) video controller fault which consisted of
reducing video subsystem performance.
This BIOS reveision was never produced, but is used to correct problems at field
level.
Rev. 1.19

NOTE:
Nearly 5,000 systems have been manufactured specificlly for the Italian Subsidiary. Following are
the major differences between these models and those of the standard production:
- System board: Some systems have been equipped with a system board that can only
support the 33 MHz 80386 SX CPU.
- Hard disk:
These systems do not come with a hard disk installed at the factory. The
first hard disk on these systems must be installed by the field engineer using
one of the following kits:
- HDU 85/M, 20 85 MB HDUs
- HDU 170/M, 20 170 MB HDUs
- HDU 240/M, 20 240 MB HDUs
- Streaming tape: These systems use an 80/120 MB streaming tape drive with a floppy interface.
- Monitors:
The following monitors can be used - DSM 25-415, 14" color
- DSM 27-214, trimode color
- Bus:
Due to the problems with the casing of these systems, the joystick
connectors:
and I/O board second serial port connectors must be mounted on a
board which is installed in one of the expansion slots. This means that the
system looses one expansion slot.
Therefore:
- For systems with slim case, of 5 slots 2 are available.
- For systems with minitower case, of 8 slots 5 are available.

TABLE OF COMPATIBLE HARD DISK DRIVES
The system’s configuration utilities contain fields in which to define the type and operating
parameters of the hard disk drive installed in the system.
The BIOS already contains the parameters of the different hard disk drives.
For the hard disks certified by Olivetti, you will need to select hard disk type 47, 48 or 49 and manually define the parameters of the hard disk installed using the →and ← keys.
The following table gives the different parameters of these hard disks.

This release contains version 1.06 of the EMMBOX2 file. The modification was
made necessary since version 1.05 of the EMMBOX2 file, contained in the
previous User Disk version, caused the system to crash when configured with 64
KB + VGA of shadow memory and 128 KB of expanded memory.
In fact, part of the E000 segnment (area reserved for the BIOS) is incorrectly
occupied by expanded memory thus causing the system to crash.

BUILT IN SETUP and EXTENDED SETUP Utilities
BUILT IN SETUP
This ROM BIOS-resident program allows you to change some of the Personal Computer’s
configuration parameters.
Two cases can arise:
First case: If the data stored in the CMOS RAM is no longer valid or the power supply battery is low,
the BULIT IN SETUP screen is displayed. You are now give the choice of selecting the language to
work in from a total of six languages available.
Second case: If the configuration of the system has been changed, only the icon representing the
device that has to be added to, or modified in, CMOS RAM will be displayed. For example, if you install a second floppy disk drive, just the floppy disk icon will be displayed.
In both cases the BUILT IN SETUP screen is automatically displayed without operator intervention.
F1
Allows you to change the system hour, minutes and seconds.
F2
Allows you to change the system day, month and year.
F3
Allows you the type of hard disk installed and its capacity. Press the space bar until the
correct value is displayed. The following table lists the hard disks that can be installed in
the system.
